So imma rank some mons since the meta is definetely going to shift quite a bit now that the moth is gone.
-> A/A+
I nominated this before for A+ rank, but now I think it is much deserved. With one of its better checks (volc checked valiant guys) gone, valiant is riding high. It now doesn't have to worry about volc setting up on it or checking special sets, while physical sets don't have to worry about cc proccing burn. This allows it to diversive more, as moonblast + fighting coverage covers most things (besides ghold), so it can experiment more instead of having to worry about hitting volc. For example, fire punch is a great move on sd sets due to it threatening ghold and other steel types in the meta, which volc would wall decently well. It also is one of, if not the single, best speed control options in the game. Getting above valiant's speed tier is a large reason why scarfrai and moon are so good, they can outspeed the most common speed control option. Combine this with the variety of options it has, and valiant to me is an easy A+ rank mon.
-> B/B+
Zapdos can fill a similarish role in spreading status onto physical attackers and loves that grass types are going to be more popular. It also beats two fairy types in primarina and valiant that will most likely rise. Zapdos in general I feel is underrated, with it still being a really great mon that despite some troubles, can put in the work. It hits quite hard but a set I am interested in is tera water blast. You can counter waterpon a lot easier, since power whip makes contact and getting a paralysis is a good trade, while dealing with the pesky ground types that might wall zap such as Sp.Defense Gliscor and clodsire. But even besides that thought, zapdos looks pretty good into the meta with it helping against waterpon, sd valiant, primarina, rillaboom and zama (which will most likely drop stone edge, making it one of the best counters if it does). We can also expand this list to cinderace, dragapult, dragonite, kingambit, meowscarada, roaring moon and hamurott if we include static. This is an impressive list to help against, and I think zapdos deserves to rise.
-> B+/A-
Hardy har har, the heatran guy is nominating for heatran to rise, what an unexpected twist. But for real, Heatran is better than ever as it no longer has to attempt and then fail at checking volc since most ran tera ground to beat it. Heatran is a monster both offensively and defensively, with it straight up denying multiple mons that could overwhelm teams while still putting out offensive pressure. Honestly, lots of mons it destroys best hope to deal with it is to hope that magma storm misses. Nothing in the tier besides gouging likes taking magma storm as the high damage and chip damage cripples most things in the tier. Two sets that I have been loving are AV and tera blast fairy. AV can take basically any special hit even with only max HP investment, even always living an enamorus earth power, which is just insane, and can fire back with a multitude of attacks that can deal super effective damage to most things. Tera blast fairy traps the poison and steel types of the tier and then tera fairys and decimates everything due to its good bulk with not many super effective hits against it and ability to have super effective coverage against a lot of the tier.
But speaking of things it helps against (up to B+ rank), that is:
Kingambit
Gholdengo
Standard gliscor set if its running air balloon
Raging bolt
Glowking
Darkrai
Hatterene
Rillaboom
Weavile
Enamorus (just scout for e-power)
Tera groundless Iron Moth
Skeledirge
Cinderace
Corviknight
Iron Crown
Ogerpon (normal variant)
Serperior
Skarmory
That is an absolute massive list of mons it helps against, and I think its time to wake up sheeple, Heatran is goated. #Goatran

Hot take, alolomola ain't an A rank mon, it's a A- rank mon. Firstly, it lets waterpon in for free and has to make big consensions just to not be the freest (that's a word) set up opportunity for it. Since waterpon is a mon you absolutely DO NOT want to give setup to, this is already a big detractor. It also has to be very standard in its moveset as any alterations, while they can be made, reduce its effectivness. It needs wish and scald, but then mainly chooses protect and flip turn into its moveset, but wants mirror coat, acrobatics, whirlpool and chilling water. If it drops protect or flip turn for another move in order to be less passive, then it is giving up on something vital. Lastly, it is passive AF, honestly too passive. Again, lets in waterpon, but many special attackers can switch in on the wish turn and set up, as they are not too threatened by it. Compare that to something like clodsire, who also is passive, who at the very least can get hazards up or toxic something. Now, the massive wishes, ability to soft check a lot of things and scald burns do make it good, but those downsides are big and don't make it an A rank mon.
